iMPACT, 9.2i - Is it possible to program a Spartan-3AN device with a design created for Spartan-3A?


I have a working design for a board with a Spartan-3A device on it. I would like to port this design to Spartan-3AN with no changes on the board and same device density. Are there any changes required for my design? Can I use the Spartan-3A bitstream to configure the Spartan-3AN FPGA?


Spartan-3A and Spartan-3AN FPGA dies are identical. The difference is that the Spartan-3AN devices include a non volatile configuration PROM (SPI Flash) stacked in the package.

In order to improve Spartan-3A migration to Spartan-3AN devices, iMPACT support to enable configuration of Spartan-3AN devices with a Spartan-3A design is being added.

The first software version enabling this feature for iMPACT is 9.2.04i.
